A sports ball comprising a transparent outer wall surrounding a hollow cavity and defining a geometric center, and a central core object suspended at the geometric center of the hollow cavity. The ball may have the shape of a sphere having a center point, with the central core object suspended at the center point of the sphere. In other cases, the ball may be oblong or ellipsoid, with the central core object suspended at the center points of the respective major and minor axes of the ellipsoid. The transparent outer wall of the ball may be elastically deformable, and may be comprised of a transparent inflatable bladder contiguous with an inner surface of a transparent outer skin. The transparent outer skin may be comprised of a plurality of outer facets joined together, such as by sewing.

Disclosed is a method for inflating packaging airbags. The method for inflating the airbags include the steps of coupling an inflation port of the airbag to a nozzle of the inflation system, wherein a collar of the airbag adjacent to the inflation port lies between the cushions of the inflation system, the cushions are a part of pair of clamps. Thereafter the inflation system can be turned on resulting in clasping of the collar by the pair of clamps. The air compressor of the system operates to supply air under pressure to the airbag through the air pressure regulator. Once the airbag is inflated, the inflation system can be turned off, resulting in releasing of the pair of clamps, thus releasing the airbag.

Described are balls, in particular a football, and a method for its manufacture. The ball comprises particles of an expanded material. As examples, the particles are connected, at least partially, to each other by radio frequency welding and/or infrared welding. As examples, the ball has a first layer of the particles of the expanded material, wherein the first layer is provided as an outer shell.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.
